The Many Facets Of Hybrid Supercomputing As Exascale Dawns
There may not be a lot of new systems on the November 2020 edition of the Top500 rankings of supercomputers, but there has been a bunch of upgrades and system tunings of machines that have been recently added, expanding their performance, as well as a handful of new machines that are interesting in their own right. …

Workers KV – free to try, with increased limits!
In May 2019, we launched Workers KV, letting developers store key-value data and make that data globally accessible from Workers running in Cloudflare’s over 200 data centers.
Today, we’re announcing a Free Tier for Workers KV that opens up global, low-latency data storage to every developer on the Workers platform. Additionally, to expand Workers KV’s use cases even further, we’re also raising the maximum value size from 10 MB to 25 MB. You can now write an application that serves larger static files directly or JSON blobs directly from KV.
Together with our announcement of the Durable Objects limited beta last month, the Workers platform continues to move toward providing storage solutions for applications that are globally deployed as easily as an application running in a single data center today.
What are the new free tier limits?
The free tier includes 100,000 read operations and 1,000 each of write, list and delete operations per day, resetting daily at UTC 00:00, with a maximum total storage size of 1 GB. Operations that exceed these limits will fail with an error.
Additional KV usage costs $0.50 per million read operations, $5.00 per million list, write and delete operations Continue reading

Upcoming Webinar: Network Troubleshooting
I’m teaching a webinar on troubleshooting theory on the 20th; register here. From the course description:
This training focuses on the half-split system of troubleshooting, which is widely used in the electronic and civil engineering domains. The importance of tracing the path of the signal, using models to put the system in context, and the use of a simple troubleshooting “loop” to focus on asking how, what, and why are added to the half-split method to create a complete theory of troubleshooting. Other concepts covered in this course are the difference between permanent and temporary fixes and a review of measuring reliability. The final third of the course contains several practical examples of working through problems to help in applying the theory covered in the first two sections to the real world.
Casual Dress Considered Harmful?
I remember a time long ago—but then again, everything seems like it was “long ago” to me—when I was flying out to see an operator in a financial district. Someone working with the account asked me what I normally wear… which is some sort of button down and black or grey pants in pretty much any situation. Well, I will put on a sport jacket if I’m teaching in some contexts, but still, the black/grey pants and some sort of button down are pretty much a “uniform” for me. The person working on the account asked me if I could please switch to ragged shorts, a t-shirt, and grow a pony tail because … the folks at the operator would never believe I was an engineer if I dressed to “formal.”
Now I’ve never thought of what I wear as “formal…” it’s just … what I wear. Context, however, is king.
In other situation, I saw a sales engineer go to a store and buy an entirely new outfit because he came to the company’s building wearing a suit and tie … The company in question deals in outdoor gear, and the location was in a small midwestern town, Continue reading
Apple Silicon M1 Chips and Docker
Revealed at Apple’s ‘One More Thing’ event on Nov 10th, Docker was excited to see new Macs feature Apple silicon and their M1 chip. At Docker we have been looking at the new hypervisor features and support that are required for Mac to continue to delight our millions of customers. We saw the first spotlight of these efforts at Apple WWDC in June, when Apple highlighted Docker Desktop on stage. Our goal at Docker is to provide the same great experience on the new Macs as we do today for our millions of users on Docker Desktop for Mac, and to make this transition as seamless as possible.
Building the right experience for our customers means getting quite a few things right before we push a release. Although Apple has released Rosetta 2 to help move applications over to the new M1 chips, this does not get us all the way with Docker Desktop. Under the hood of Docker Desktop, we run a virtual machine, to achieve this on Apple’s new hardware we need to move onto Apple’s new hypervisor framework. We also need to do all the plumbing that provides the core experience of Docker Continue reading
Running Kubernetes on VMWare: Challenges and Solutions
Kubernetes on VMware is still more complex and less performant than plain Kubernetes installed on your own bare metal services or directly on VM instances in public cloud providers.Network Break 310: Kemp Acquires Flowmon; Networking Startup Isovalent Nabs $29 Million VC Bucks

The Week in Internet News: A Change in U.S. Internet Policy?
Winds of change: U.S. President-elect Joe Biden will significantly change U.S. government policy focused on the Internet, Vox.com says. A Biden administration is likely to bring back net neutrality rules and push for policies that widen Internet access and make it more affordable. The Biden team may also provide more subsidies to lower-income people and open up more radio frequency bands for high-speed 5G networks.
Accessing growth: The growth of Indonesia’s digital economy depends on equal access to the Internet, but 12,000 villages across the country still lack access, Kompas.com reports. Indonesia’s Finance Minister Sri Mulyani Indrawati is pushing for digital infrastructure to be distributed throughout the country. The government has a 2021 budget of 30 trillion rupiahs ($2.1 billion USD) to develop information and communication technology infrastructure.
Lowering the Zoom: Video-conferencing service Zoom has settled a U.S. Federal Trade Commission complaint saying that it overstated its encryption protections for several years, TechCrunch says. “Zoom’s misleading claims gave users a false sense of security … especially for those who used the company’s platform to discuss sensitive topics such as health and financial information,” the agency said. Zoom has agreed to start a vulnerability management Continue reading
AMD At A Tipping Point With Instinct MI100 GPU Accelerators

New Content: Graph Algorithms – Flows and Connectivity
Last week we enjoyed the second half of Graph Algorithms lecture by Rachel Traylor, this time focusing on flow- and connectivity challenges.
After an easy start defining flows and walking us through various maximum flow algorithms, Rachel explained circulations and saturating flows, switched into high gear with (supposedly painless) intro to linear programming and minimum cost flow problems, and concluded with dynamic flows and using flows to explore graph connectivity.
